Steps of the invention are that an agitator in a main reaction region is started while water enters to implement the nitrification process under the hypoxic condition. When a maximum value appears on a pH value curve and an inflection point appears on an ORP curve, the stirring is stopped. When the last stirring stage is stopped, oxygen is added in the mixture for the degradation of organic compounds and the nitrification of nitrogen compounds. When a minimum value appears on the pH value curve, the aeration is stopped. The steps are repeated till the water inletting stage is finished. And an aerobic aeration stage is taken as an ending stage of a reaction period.
